Packard 733 Series Tires

Packard 733 Series uses two listed tire sizes for 1930: 32X6.20 and 650-20. The 32X6.20 size is an antique diameter-by-section format, while 650-20 is a numeric bias-ply size. Both correspond to 20-inch rims, so the difference is not a wheel-diameter change but a change in size convention and tire profile.

The practical step is to inspect the wheel and the size already on the car, then compare that with the type of restoration you are aiming for. A car preserved in an earlier-style fitment may call for the antique-size approach, while a car already running a numeric 650-20 setup should stay with that format unless the wheel and overall combination are being changed deliberately.

On a Packard 733 Series, 32X6.20 is an antique diameter-by-section size. The first number, 32, refers to the tire's overall outside diameter in inches, not the wheel diameter. The second number, 6.20, is the section width, and the wheel used with this fitment is 20 inches.

That distinction matters because a modern buyer can easily mistake the 32 for the rim diameter, which would be incorrect. When working with antique-size markings on a Packard 733 Series, use the wheel itself and the stated rim specification to verify fitment, then decide whether you want to preserve the period-correct size format already used on the car.

Packard 733 Series uses a 20-inch rim for both listed 1930 tire sizes. That includes the antique-size 32X6.20 and the numeric 650-20. Even though the antique code begins with 32, that number describes tire diameter rather than wheel diameter.

This is the first detail to confirm before comparing sidewall styles or tread families. If the wheel on your Packard 733 Series measures 20 inches at the bead seat and the existing tire size matches one of the listed conventions, you are on the right track; if not, inspect for later wheel changes or a prior owner conversion before choosing replacement tires.

Packard 733 Series fitments in this range are bias-ply designs, and the 650-20 offerings are tube-type applications. That means a tube is required with the numeric bias-ply 650-20 fitment. For a pre-war car such as Packard 733 Series, tube-type construction is the normal expectation when using these period-style tires.

Tube fitment is not just a technical detail; it affects mounting parts, air retention, and the overall correctness of the installation. When servicing a Packard 733 Series, inspect the wheel condition, valve hole, flap requirements if applicable, and the inside of the casing so the tube and tire work together as intended on a low-use collector car.

A 1930 Packard 733 Series can appear with either 32X6.20 or 650-20, and both use 20-inch rims. The right choice depends on which size convention your car is set up for and what is currently fitted to the wheels. The existing tire marking, the wheel dimensions, and restoration records are the best clues.

Start by reading the old sidewall if possible, then inspect the wheel carefully during dismounting. If the car has been restored before, review any judging sheets, shop records, or marque references tied to that specific automobile. That process is more reliable than choosing only by model year, because Packard 733 Series appears with two size conventions in the same year.

Packard 733 Series products in 650-20 are available in both blackwall and wide whitewall form. The whitewall option listed here is a 3.75-inch whitewall, while several other products in the same size use blackwall construction. That gives owners a choice between a more formal luxury appearance and a plainer utility look.

For a restoration, the best sidewall style depends on how the specific Packard 733 Series is being presented. A formal restored car may call for the visual presence of a whitewall, while a more utilitarian or commercial-looking setup may lean toward blackwall. Match the sidewall style to the car's intended character and any period references you are following for that particular example.

Packard 733 Series tire options here come from Firestone, Denman, and Deka. Firestone covers both passenger-style classic bias-ply offerings and a truck-tread option in 650-20, while Denman and Deka appear in truck-oriented 20-inch bias-ply products. That mix gives the 650-20 size the widest brand coverage.

Brand choice should follow the role of the car rather than badge preference alone. If your Packard 733 Series is being restored as a traditional passenger car, the classic passenger-style bias-ply offerings will usually make more visual sense. If it is being assembled around a heavier-duty or utility-oriented presentation, the truck-style products may be the more appropriate comparison.

Packard 733 Series products here include Firestone Classic Bias Ply, Highway Classic Truck, Deka Classic Truck, and Firestone Classic Truck series. The Firestone Classic Bias Ply line represents a traditional passenger-car style, while the truck series names point toward heavier-duty tread families and a more utility-oriented appearance. All of the listed products are bias-ply construction.

That distinction matters because a Packard 733 Series can be restored with different priorities. A car judged on passenger-car authenticity will usually favor the classic bias-ply passenger series, especially where whitewall styling is desired. A car using a more rugged visual theme or needing a truck-tread style should be compared carefully by tread pattern, sidewall look, and overall period presentation.

Packard 733 Series should be stored in a cool, dry, dark space with the tires protected from sunlight, ozone sources, and petroleum contamination. Keep the car on a clean surface, maintain proper inflation, and avoid long-term exposure to electric motors, battery chargers, or heaters that can accelerate rubber aging. For a pre-war collector car, stable conditions matter as much as mileage.

If the Packard 733 Series will sit for extended periods, roll it occasionally to change the contact patch or support it in a way that reduces prolonged flat spotting without stressing the suspension. Clean the tires with mild soap and water only. Aggressive dressings and solvents can shorten the life of period-style sidewalls and make future inspection more difficult.

Tires on a Packard 733 Series should be inspected before each drive and more thoroughly at regular service intervals even if the car covers very few miles. Check air pressure, sidewall cracking, tread separation, bead condition, tube-related air loss, and any change in how the car sits or steers. Low annual mileage does not stop rubber from aging.

A pre-war Packard benefits from a slower, more deliberate inspection routine than a modern driver car. If you notice vibration, pull, unusual wear, or repeated pressure loss, remove the wheel and inspect the tire and tube assembly rather than continuing to drive on it. Collector tires often age out long before they wear out, so visual and hands-on checks are essential.

Packard 733 Series tires should be replaced when age, cracking, hardening, separation, persistent air loss, or casing damage appears, even if the tread still looks usable. Tread depth alone is a poor guide on collector cars because they often spend more time parked than driving. Rubber condition and structural health matter far more than remaining pattern depth.

That principle is especially important on a pre-war Packard because period-style tires can look presentable while becoming brittle internally. If the car carries an older assembly of uncertain age, have each tire evaluated during dismounting so the beads, inner liner area, and tube surfaces can be examined closely. Replace on condition and age, not simply when the tread appears worn.

Packard 733 Series is associated here with two 1930 size conventions: 32X6.20 and 650-20. That indicates owners may encounter either an antique diameter-by-section fitment or a numeric bias-ply fitment on cars from the same model year. The available products also show both passenger-style classic bias-ply and truck-oriented series within the 650-20 size.

For restoration work, the most accurate path is to match the specific Packard 733 Series in hand rather than relying on year alone. Surviving wheel equipment, older photographs, restoration records, and Packard club references can help determine whether your car should retain an earlier-style size convention or a later numeric bias-ply presentation for authenticity and judging purposes.

Correct tire fitment can absolutely affect how a Packard 733 Series is judged and perceived, especially on a pre-war luxury automobile where stance, sidewall style, and overall period character are highly visible. Judges and informed buyers often notice whether the tire size convention, sidewall treatment, and general profile suit the era of the car.

A Packard 733 Series restored with the right diameter, width impression, and sidewall appearance will usually look more settled and convincing than one wearing a mismatched modern-looking substitute. If the car is being prepared for competition or high-level presentation, compare your tire choice against period photographs, marque-club guidance, and the actual wheel setup before final assembly.

Packard 733 Series tire options here include both blackwall and wide whitewall styles in 650-20. Either can suit a pre-war restoration depending on the character of the specific car, but the visual result is quite different. Whitewalls emphasize formal luxury presentation, while blackwalls create a more restrained and utilitarian period look.

The correct choice for a Packard 733 Series should follow the way the car is being restored rather than fashion alone. Review period images of similar cars, any surviving history of your specific example, and the overall trim level and presentation. Sidewall style has a major effect on stance and authenticity, so it is worth deciding early before the rest of the car is finalized.

Period-style bias-ply tires can be appropriate for driving a Packard 733 Series on public roads when they are correctly fitted, properly inflated, and in sound condition. Their behavior will not match a modern radial, and a pre-war chassis places its own limits on speed, braking, and emergency maneuvering. Safety depends on the whole vehicle being sorted, not just the tire itself.

Treat road use in a Packard 733 Series as deliberate vintage motoring rather than modern traffic performance. Before regular driving, make sure the wheels, tubes, steering, brakes, alignment, and suspension are all inspected to the same standard as the tires. A careful mechanical review and conservative use are the right companions to any period-correct tire choice.

Before driving a Packard 733 Series, check tire pressure, visible sidewall condition, wheel security, valve stems, and whether the car sits evenly on all four corners. Also inspect for cracks, cuts, bulges, and any sign of tube-related leakage or bead distress. Because this is a 1930 automobile, tire checks should be part of a broader walk-around that includes brakes, steering, and fluid leaks.

A short inspection before every outing can prevent damage to scarce parts and reduce the chance of being stranded with a tube-type tire issue. If the Packard 733 Series has been parked for a long period, move it slowly at first and pay attention to steering feel, vibration, and brake pull. Any unusual behavior is reason to stop and inspect before continuing.

A Packard 733 Series on period-style bias-ply tires should be driven at moderate, conservative speeds that respect both the tire design and the capabilities of a 1930 chassis. Even when the tires are new, the car's braking, steering response, and road manners remain those of an early pre-war automobile. Comfortable touring speed matters more than keeping pace with modern traffic.

The sensible approach is to build speed gradually and stay within the range where the Packard 733 Series feels settled, predictable, and easy to stop. Avoid sustained high-speed running, abrupt lane changes, and rough road impacts. If the car wanders, follows grooves, or develops heat and vibration, slow down and inspect the tire and chassis setup before further road use.
